If it only happens with some discs and not all, I doubt there is
anything wrong with your drive, but the fault is with some discs. The
easy way to confirm this is try playing them in another computer and
see if that computer too makes "funny sounds" trying to play it.
Just because you don't see scratches doesn't mean the disc isn't
damaged. Those funny sounds are likely the drive going crazy trying to
seek sectors it can't access due to some corruption on the disc.
Make sure that the CD or DVD is free from all foreign material,
fingerprints, smudges, etc.. There is no practical way of repairing a
damaged CD/DVD. If it is a one of a kind you don't have a replacement
for you best bet is to try to copy what files you can from it using
the Command Prompt assuming the disc can be read at all.
I have had a terrible problem with a LiteOn SH-16A7S (brand new SATA DVD-RW
drive). It exhibited very similar symptoms. A fairly significant
proportion of my movie discs were simply not recognised as being present in
the drive. (I haven't come across a data DVD or CD that wasn't recognised,
but that's not to say they don't exist). The drive would spend a while
spinning them and looking over and over, and eventually give up. [The
computer did not freeze during this searching though as the OP seemed to
observe]. In my case I really do believe there is something wrong with the
drive, as the discs which are not registered in the drive all work perfectly
in my other drive (10-year-old PATA Hitachi DVD ROM drive). I had the drive
replaced with another of the same type which showed exactly the same
problem. I am about to exchange it for a completely different make &
model - Samsung SH-S203. If anyone has any bad experiences with this drive
please reply here, and I'll select something else.
